A represents the cylinder, constructed of any proper material andsuitable size, and provided with the longitudinal central perforatedtube a, as shown. a1 a2 represent cocks, by means of which the air maybe exhausted from the cylinder, and the oil introduced when desired. a3represents a cock regulating rthe admission of substances into thecentral perfora-ted tube ct. The cylinder A may be supported on wheels,as shown in Fig. l, in such a manner as to be removed therefrom, ifdesirrd. H represents a filter, by means of which any large substance isprevented from entering the cylinder.

The mannerof usingmyimproved apparatus is as follows: A vacuum is formedin the cylinder in any proper manner; it is then connected ywith theoil-tank, and, the proper cock being opened, the oil is drawn up intoit. After being permitted to remain in this condition for six or eighthours, more or less, according to the character of the oil, the cylindermay be exposed to heat, proper bleaching chemicals being injectedthrough the central perforated tube while it is being heated. By meansof this apparatus the oil is boiled at a low temperature, and much fuelis saved thereby.
